The Hirose HSC-A2-D1(01) is a simplex SC-to-SC coupler from the HSC series, designed to align and join two SC-terminated fiber patch cables in a panel-mount installation. It accepts an SC connector on both ends — the Convert From and Convert To adapter ends are both SC Receptacle — making it a straight-through inline adapter for single-fiber links. The blue housing is the standard color identifier for single-mode simplex adapters in the Hirose HSC line.
Construction and Mounting
The coupler uses a zirconia ferrule for precise fiber alignment and low insertion loss — zirconia is the industry standard for durable, low-wear alignment sleeves in SC adapters. Mounting is via panel mount with flange and snap-in retention; the coupler pushes into a rectangular cutout and locks without hardware, which speeds installation in telecom enclosures and patch panels.
This rating is a standard requirement for telecom central-office and data-center patch panels.
The HSC-A2-D1(01) is in Last Buy status per the manufacturer lifecycle record. This means Hirose has announced end-of-production and the remaining stock is the final available supply.
The coupler mates with any standard SC connector on both ports — both ends are SC Receptacle. This includes SC simplex connectors terminated on single-mode or multimode fiber, as the adapter body is connector-format-specific, not wavelength-specific. The dust cap (listed as a feature) protects the alignment sleeve when the ports are not in use. For a field-service technician replacing a damaged coupler in a patch panel, the snap-in panel mount allows tool-less swap-out from the front of the panel.
